Model SP | Model SP-P
The Pro-Equipment Grit-Guard provides a cost effective means for washing, dewatering and conveying separated grit or sand from wastewater. This rugged Headwork’s Classifier offers two model types.
Receives grit from grit separation system to be further washed, dewatered and conveyed
Screw conveyor transports collected grit through inclined trough to discharge at the upper end
Tank, trough, and screw conveyor made of 300 series SS. High strength steel augur is an option
Wide range of tank sizes to handle specific grit slurry loads
Top mounted cyclone available to increase removal of finer grit particles and reduce hydraulic load to classifier
Grit-Guards standard Grit Washing Classifier comprised of a collection tank and a motor driven inclined screw conveyor. The tank walls are uniquely shaped and engineered to accommodate the conveying trough.
Carbons all the features and grit handling capabilities as the Model-SP, plus has an additional washing agitator for applications that require additional grit washing.
When installed near a grit chamber, both Grit-Guard models return separated water back into the grit chamber. Water, free from sediments, but containing some organics, is streamed through an overflow trough were a connecting pipeline transfers it to the next treatment process stage.
The Stainless Steel Grit-Guard models are manufactured to deliver long service life in either indoor or outdoor locations. When installed outdoors, the Grit-Guard can be equipped with both insulation and an electrical heater to hold-up to harsh, inclement weather. An open-air thermostat is also available to operate the heating element during the winter season.
Grit is agitated, washed and conveyed up an inclined open trough by a Helix Screw that’s powered by an electric gear motor. The spiral rotating Helix Screw efficiently moves separated materials up the trough where it is discharged through a top chute falling into a receptacle for final disposal.
